Error 'The attachment could not be added to the message' when uploading files under Windows 2003

SYMPTOMS

Error 'The attachment could not be added
to the message' occurs when uploading files under Windows 2003.

The additional error string reported
is:

File save failed for the following reason:
C:\Program Files\MailEnable\POSTOFFICES\\MAILROOT\\Drafts\ is an invalid
path

The following error may also
display:

Error MEUP001: The ASP
Session expired during the upload.

CAUSE

IIS6.0/Windows 2003 uses
a setting called 'AspMaxRequestEntityAllowed' to specify the maximum number of
bytes allowed in the body of an ASP request. File uploads may contain more
data than the 200K allowed by the default setting, and therefore this maximum value will need to be increased.

RESOLUTION

1. Stop the World Wide Web Publishing Service. This can be done from the
Windows Command Prompt as: net stop w3svc 2.
In the C:\Windows\System32\Inetsrv directory, locate a file called
metabase.XML.3. Copy the original file into Notepad and find the line
"AspMaxRequestEntityAllowed"4. Change the value of this entry to "1073741824".
(This specifies a maximum post size of 1 GB) 5. Save
the file 6. Start the World Wide Web Publishing Service. This can
be done from the Windows Command Prompt as: net start
w3svc

Note: If the Metabase.XML file is
locked, try starting Windows in Safe-mode to be able to change that file.
